▎ 摘　　要

NOVELTY - The core has a sheet-shaped metal net whose surface is formed with a sputtered film that is formed by graphene material. The sheet-shaped metal net and the sputtering film are installed in an inner wall of a metal tube shell. Diameter of the sheet-shaped metal net is about 0.025mm-0.045mm. The thickness of the sputtering film is about 180nm- 220nm. USE - Heat pipe core for a heat pipe (claimed). ADVANTAGE - The core improves response time during heat pipe phase change process so as to improve efficiency of heat exchange so that phase transition time period id reduced, thus reducing temperature difference of a heat pipe hot end and cold end, and hence improving heat conducting power. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a heat pipe sputtering method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a heat pipe core.
